November 17, 2021How to provide `setupFilesAfterEnv` to jest when using jest builder.
Angular currently does not support modifying the Jest config or CLI options (that comment refers to Angular providing it's own options to Jest, not exposing them to users). You might be able to get away with adding jest-canvas-mock to test polyfills, I think that runs as part of setupFilesAfterEnv. Otherwise I'd suggest writing the test in such a way to not use Canvas, given that it isn't supported in Jest and the mock doesn't actually do anything meaningful. Also consider sharing your use case on https://github.com/angular/angular-cli/issues/25434 More on reddit.com

Is Angular Testing Library compatible with Angular 17 and standalone components?
Yes, but compatibility depends on the library version. Angular Testing Library continues to evolve alongside Angular, and newer versions support modern Angular features like standalone components. However, as with Jest in Angular 16–17, some integrations may still be evolving or require careful version alignment, so it’s important to verify compatibility between Angular, Jest, and Testing Library versions before implementation.

How to install Jest and Angular Testing Library
What is Angular Testing Library and how does it differ from TestBed?
Angular Testing Library is a lightweight set of utilities that helps you test components from the user’s perspective, focusing on behavior rather than implementation details.In contrast, Angular’s TestBed is a more traditional, configuration-heavy tool that mirrors Angular’s internal module system. Testing Library simplifies setup and encourages more maintainable tests by reducing direct interaction with component internals.

r/angular on Reddit: Is Jest still going to be integrated officially with Angular?
March 3, 2025 -
I've been having a nightmare trying to reconfigure an old project's tests from Jasmine/Karma to Jest, because I have many coworkers advocating for it. But I'm surprised to see that while Karma has been deprecated for almost 2 years now, ng new and the refreshed Angular docs still only go over Karma, and make no mention of Jest or other testing frameworks at all https://angular.dev/guide/testing#other-test-frameworks.
This announcement https://blog.angular.dev/moving-angular-cli-to-jest-and-web-test-runner-ef85ef69ceca mentions @angular-devkit/build-angular:jest but I'm not sure if that's worth using - googling it actually points me to https://www.npmjs.com/package/@angular-builders/jest first but I'm not sure if this is something official.
jest-preset-angular also appears in lots of guides but it seems like every guide has a different way to set that up and I find its documentation kind of a nightmare of its own. Doesn't feel particularly futureproof.
Is Jest going to be a passing fad for Angular? Is there any news of deeper, documented integration anytime soon? Is Web Test Runner support at least close to being ready?

Jest relies on jsdom, which is missing polyfills for things that Chrome has implemented and are widely used by libraries. So anyone using Jest that has a dependency that uses TextEncoder has to decide if they want to write their own polyfill, switch to happydom, or remove the dependency, or my colleague’s favorite method - deleting affected .spec files.

In angular.json file specify jest runner for test architect:
"test": {
"builder": "@angular-builders/jest:run",
"options": {}
},
I assume that you have installed it, when switched to jest

- Created a setupJest.ts file in the root and import jest-preset-angular
- add the Jest configuration in the package.json
"jest": {
"preset": "jest-preset-angular",
"setupFilesAfterEnv": [
"<rootDir>/setupJest.ts"
]
}modify the test script to use Jest instead of ng test.
